Name That Trauma:: Suzanne D. on a Submerged Crane Quarry Monster

Okay, I've got one for you that's been driving me crazy for years. I think it may have originally been a Disney movie, back when Disney wasn't afraid of going to the darkside from time to time. It had to come from the early '80s, based on when I remember seeing it. The plot involved a monster living in the bottom of a water-filled quarry. All I really remember about this, other than the fact that it really scared me as a kid, was that the monster turned out to be a crane (of the mechanical type, not the bird). I know the lead character was a little boy. My warped memory keeps turning the kid into Barrett Oliver, even though I know it wasn't him. If you or any of your followers could ID this film for me, I would be most grateful. I've been trying to remember for over twenty years and I just can't come up with a title!

Thanks!

UNK SEZ: Thanks for writing in, Suzanne. I do believe that I've found what you are looking for. It stars E.T.'s Henry Thomas and was released in 1986. It's known as FROG DREAMING in its native Australia, THE GO-KIDS in the United Kingdom and here in the states it went by THE QUEST. I'm happy to tell you that it's available on YouTube so you can revisit your kindertrauma below!
